Funding rate

SQL API

api.funding_rate

Funding-rate history for perpetual swaps across supported exchanges. Markets are exposed under their universal symbol (e.g. BTC-USD-PERP-INV for the BTC-margined inverse perp, BTC-USDT-PERP for the USDT-margined linear), with the originating exchange and contract type recorded alongside the rate. Inverse perps carry an -INV suffix to keep them distinct from any linear product with the same (base, quote) pair.

The settlement period varies per exchange. Deribit publishes funding hourly with continuous accrual; Binance, OKX, and Bybit publish discrete 8-hour events (some markets settle every 4h or 1h). Consumers should infer the period from the gap between consecutive timestamps for the same (exchange, market) pair.

The REST /funding-rate endpoint requires both market and exchange. For cross-exchange comparisons in a single query, use the SQL API.

Columns

Column	Type	Description
exchange	LowCardinality(String)	Exchange that published the funding event (binance, bybit, okx, deribit)
contract_type	LowCardinality(String)	LINEAR_PERPETUAL (USDT/USDC-margined) or INVERSE_PERPETUAL (coin-margined)
market	LowCardinality(String)	Universal perpetual symbol (e.g. BTC-USD-PERP-INV, ETH-USDT-PERP)
timestamp	DateTime64(9, 'UTC')	Settlement timestamp
funding_rate	Decimal(76, 20)	Rate that accrued in the period ending at timestamp

Example Queries

1. Latest BTC-USD-PERP-INV funding across exchanges

SELECT
    timestamp,
    exchange,
    contract_type,
    funding_rate
FROM api.funding_rate
WHERE market = 'BTC-USD-PERP-INV'
  AND timestamp >= now() - INTERVAL 24 HOUR
ORDER BY timestamp DESC, exchange ASC
LIMIT 50

Functions used: now.

2. Cross-exchange funding spread

Compare the most recent settled funding rate per exchange for one market:

SELECT
    exchange,
    argMax(funding_rate, timestamp) AS last_rate,
    max(timestamp) AS last_settled_at
FROM api.funding_rate
WHERE market = 'BTC-USD-PERP-INV'
  AND timestamp >= now() - INTERVAL 7 DAY
GROUP BY exchange
ORDER BY last_rate DESC

Functions used: argMax.

3. Realized 24h funding cost on a long position

SELECT
    market,
    exchange,
    sum(funding_rate) AS realized_24h_funding
FROM api.funding_rate
WHERE timestamp >= now() - INTERVAL 24 HOUR
  AND market IN ('BTC-USD-PERP-INV', 'ETH-USD-PERP-INV', 'SOL-USD-PERP-INV')
GROUP BY market, exchange
ORDER BY market, exchange

A long pays funding when funding_rate > 0 and receives it when funding_rate < 0. Multiply by position notional to convert to fiat.

REST API

Get funding rates for a perpetual market

get

Funding-rate history for perpetual swaps across supported exchanges.

The settlement period is exchange-specific. Deribit publishes funding hourly (continuous accrual); Binance, OKX, and Bybit publish discrete funding events every 8 hours (sometimes 4h or 1h on select markets). Consumers should infer the period from the gap between consecutive timestamps for the same (exchange, market) pair.

Supported exchange values: binance, bybit, okx, deribit. For cross-exchange queries, use the SQL API.

This endpoint is limited to 10000 records per request.

Authorizations

x-api-keystringRequired

Required for /ohlcv and /trade endpoints. Pass your API key in the x-api-key header. Public /market/* endpoints do not require authentication.

Query parameters

marketstringRequired

Koinju canonical perpetual symbol. Inverse perps carry the -INV suffix (e.g. BTC-USD-PERP-INV for the BTC-margined USD-quoted perp); linear perps don't (BTC-USDT-PERP). Use /market/future to enumerate available perpetual symbols.

exchangestring · enumRequired

Exchange to filter by — one of binance, bybit, okx, deribit. For cross-exchange queries, use the SQL API.

Possible values:

start_datetimestring · date-timeRequired

Window start. Accepts any format parseable by parseDateTime64BestEffort — e.g. a plain date (2026-05-01, treated as midnight UTC) or a full ISO 8601 timestamp (2026-05-01T12:00:00Z).

Example: 2026-05-01

end_datetimestring · date-timeRequired

Window end. Same format as start_datetime. Returned rows satisfy start_datetime <= timestamp < end_datetime.

Example: 2026-05-08
